I'm in a band tadadel 2.5 A device called the Jetlev can lift a person 30 feet (9 meters) by pumping water from a backpack through a hose connected to a small, unmanned boat. Another device called the Flyboard, which looks like a small snowboard attached to a hose, can propel riders 45 feet (14 meters) in the air.
